The android APK is automatically updated with the notification and the download progress is displayed.

First, sort out the idea of automatic APK update: 1. Compare the server version with the local APK version; 2. If the server version is newer, send a notification to the user for download; 3. Click Start download; 4. After the download is complete, the user is prompted to click "Install". 5. Click "Install" to complete the entire process;

Below is, you can first check whether it is the effect you want, kiss!

OK, and then directly add the code. This document will not be mentioned after version comparison. It will start with the notification.

// Summary string tickertext = context. getresources (). gettext (R. String. app_name). tostring () + "new version found. We recommend that you update it! "; // Title String title = context. getresources (). gettext (R. string. app_name ). tostring () + "Update"; // content string content = "click to update" + context. getresources (). gettext (R. string. app_name ). tostring (); // logoint icon = R. drawable. logo; Notification = new notification (icon, tickertext, system. currenttimemillis (); intent updateinte = new intent (context, UpdateService. class); updateinte. putextra ("url", RE); pendingintent = pendingintent. getservice (context, 0, updateinte, 0); // click open service to download notification. setlatesteventinfo (context, title, content, pendingintent); notification. defaults = notification. default_sound; notification. flags = notification. flag_auto_cancel; icationicationmanager manager = (icationicationmanager) context. getsystemservice (context. notification_service); manager. Y (101, notification );

The following is the service download class. The following code has two problems. The notification version compatibility issue is reported!
